Output

The tokenizer you provided is almost correct, but it seems like it's missing an import statement for the `re` module, which is used for regular expressions. Also, it would be beneficial to add error handling for non-matching inputs. Here's the revised version:

This version of the tokenizer will raise a `ValueError` if the input string does not match the expected pattern.

Output

The tokenizer class you provided is almost correct, but it has a small issue. The regular expression used in the `re.findall` function does not properly handle whitespace characters. This might cause issues if the input string contains spaces, tabs, or newlines. Here's a corrected version of your tokenizer class:

        # Filter out whitespace tokens

    def get_next_token(self):

        return token

    def peek_next_token(self):
        if self.position >= len(self.tokens):
            return None
        return self.tokens[self.position]
This version of the tokenizer will properly handle input strings with whitespace characters. The `\s+` in the regular expression matches any whitespace character. Then, the list comprehension filters out any tokens that are empty strings, spaces, tabs, or newlines.

This version of the tokenizer will ignore any amount of whitespace before and after each token, and it will also handle floating point numbers correctly. The regular expression is also compiled once and stored for reuse, which can improve performance if you're tokenizing many strings.

Output

It seems like your tokenizer is mostly correct, but it might not be handling whitespaces properly. I'm assuming you're using the `re` module for regular expressions, which you didn't import in your code. Here's a slightly improved version of your tokenizer:

        if self.position >= len(self.tokens):
            return None
        return self.tokens[self.position]
In this version, I've added the import for the `re` module, and modified the regular expression in the `__init__` method to ignore whitespaces. The `replace(' ', '')` method is used to remove all spaces from the input string before tokenizing it. Also, I've put the operators inside a character class `[]` in the regular expression, which is a more common and readable way to define a set of characters.

assert answer == expected, f'Wrong answer; got {answer} instead of {expected}'
print('All tests passed')
And got the output: Traceback (most recent call last): File "/usr/src/app/main.py", line 27, in <module> assert answer == expected, f'Wrong answer; got {answer} instead of {expected}' ^^^^^^^^^^^^^^^^^^ AssertionError: Wrong answer; got ['s', 'i', 'n', '(', '3', '+', '2', '*', '4', ')', '-', 'c', 'o', 's', '(', '15', ')'] instead of ['sin', '(', '3', '+', '2', '*', '4', ')', '-', 'cos', '(', '15', ')']

Substring Evaluation

Testing if the previous output contains the string All tests passed: False
